Huge win for car owners! All TSBs to be made public.
The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues.
Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2013 Chevrolet Avalanche Owner Comments

Avalanche

7,100 miles

A D V E R T I S E M E N T S

My Avalanche has developed a rough idle at times ever since new. Sometimes it is rougher than other times and is not constant. I had it to the dealer two times and contacted Chevrolet support. Dealer claims there is no problem and since there are no tsb's there is nothing they can do to correct. One dealer said the fuel trim levels are very lean which causes the rough idle. I never had a vehicle with an idle like this and believe the fuel trim levels could be adjusted in the computer to smooth out the idle. Chevrolet support just directs me back to the dealer in a circle. The vehicle has not stalled out yet but I do not want that to happen which could cause a safety issue while stopped at an intersection or making a turn. The idle for a computer controlled engine in a vehicle this expensive should idle rock solid, thanks for looking into this for me.
